Place the heads in a tray for a week to dry. Then pluck the seeds from the head with your finders. Viable seeds will be fat and brown. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 90%. Seeds are non-dormant, viable seed should germinate readily.
